SELINUX: add /sys/fs/selinux mount point to put selinuxfs
In the interest of keeping userspace from having to create new root filesystems all the time, let's follow the lead of the other in-kernel filesystems and provide a proper mount point for it in sysfs. For selinuxfs, this mount point should be in /sys/fs/selinux/ Cc: Stephen Smalley <sds@tycho.nsa.gov> Cc: James Morris <jmorris@namei.org> Cc: Eric Paris <eparis@parisplace.org> Cc: Lennart Poettering <mzerqung@0pointer.de> Cc: Daniel J Walsh <dwalsh@redhat.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de> [include kobject.h - Eric Paris] [use selinuxfs_obj throughout - Eric Paris] Signed-off-by: Eric Paris <eparis@redhat.com>
